A uniform slender bar AB of mass m has two light pegs A and B
which are constrained to move in the frictionless circular slot
with center O in the vertical plane. At the position depicted, the
bar is released from rest. Find the bar's initial angular
acceleration when the bar is released in terms of appropriate given
quantities. The pegs each contact only one side of the slot at a
given time.
